Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 tuning machine delivers exceptional tuning accuracy and smooth operation with its refined 1:18 gear ratio. Designed to set the standard for enclosed tuners, it combines CNC-machined components with premium surface finishes for smooth, sensitive, and long-lasting tuning stability.
Equipped with high-grade brass posts precisely fitted into the housing, this tuning machine eliminates wear and ensures pitch stability. The stepped M6 flanged washer centers the string post reliably via the hollow screw, preventing tilt and reducing mechanical stress on both the post and rear mounting screws.
Featuring permanent internal lubrication with Schaller special grease, the M6 180 is entirely maintenance-free. Its updated housing dimensions allow seamless retrofitting and direct replacement for classic models without requiring headstock modifications.
